Scheme is applied in addition, the thin-walled hard tube 3 is thin-wall stainless steel.
In order to which pipe leakage point 7 is repaired, while in order to repair the C-shaped spring-backed quill 2 in section
With certain elasticity, it is made to be closely adhered to the inner wall of pipeline 1 by that can flick after being come out in thin-walled hard tube 3 by press
On, the preferred embodiment of the invention is in addition, the C-shaped spring-backed quill 2 in the section is plastic tube or is copper pipe.
In order to enable flexible steel wire 5 to move in the axial direction, the elasticity for pushing press ring 4 that section is C-shaped
Casing 2 releases thin-walled hard tube 3, and further preferred embodiment of the present invention is in addition, outer layer in the two sheets of flexible casing
The inner wall of casing 6 and/or the outer wall of inner tube 19 are equipped with the caulking groove of flexible steel wire 5, and the two sheets of flexible casing is nylon jacket
Pipe is plastic bushing.
The working principle of pressure conduit plugging device is the side for being repaired the leakage point of pipeline using the inside by pipeline
Method, pressure fluid flow is out-of-date when having in pipeline in this way, and pressure is bigger for repairing the spring-backed quill and pipe in the C-shaped section of leakage point
Road inner wall is bonded more secured, only need to be by the c-shaped opening staggered positions of leakage point and the spring-backed quill in the section C on pipeline
Can, such as magnetic field strength by bar magnet at c-shaped opening position is faint or is zero.Using thin-walled hard tube is made in advance, make
Its outer diameter is identical as the internal diameter of pipeline and assembles at dynamic cooperation, and the length of thin-walled hard tube is longer than the length of the spring-backed quill in C-shaped section
Degree, the length of the spring-backed quill in C-shaped section are slightly longer than the length at pipe leakage point position.First by the bullet in C-shaped section
Property sleeved compression so that c-shaped opening reduce or closure, be then loaded into thin-walled hard tube, be also equipped with and be used in thin-walled hard tube
The press ring of the spring-backed quill in C-shaped section is released, press ring is also connect with one end of more flexible steel wires, more flexible steel wire quilts
It is clamped between two sheets of flexible hose, constitutes flexible axle structure such as the bracing wire of cable brake, more flexible steel wires are in upper layer flexible pipe
The lower other end is clamped to connect with propeller, propeller by the pressure spring being mounted between the first disk and the second disk press more it is soft
Property steel wire, more flexible steel wires pass through the first disk and connect with the second disk, cross bar or handle are connected on the first disk, use
Hand holds cross bar or then handle presses the button being mounted on the second disk, so that it may which it is hard to be mounted on thin-walled by press ring
The spring-backed quill in the C-shaped section in pipe is released outside thin-walled hard tube, and the spring-backed quill in the C-shaped section being pushed out is become by confined state
For spreading state, the outer wall of the spring-backed quill in C-shaped section and the inner wall of pipeline are fitted closely at this time, due to the bullet in C-shaped section
It is attached with hot melt adhesive on the outer wall of property casing, may make the spring-backed quill and pipeline in C-shaped section as long as the outer wall of heating pipe
Inner wall is closely linked.It is just to be able to using the purpose of flexible steel wire and flexible double hose so that thin in the present apparatus
Wall hard tube continues to move ahead after can turning round in pipeline, can reach the leakage point position on pipeline, and bar magnet and magnetic force are visited
Surveying device is the detecting instrument for accurately finding the leakage position on pipeline, since magnetic survey device is just placed on letting out on pipeline
Leak source position, when bar magnet reaches the leakage point position on pipeline inside pipeline, tongue tube in magnetic survey device is by circuit
It connects, indicator light shines and lights, and at this moment can be released the spring-backed quill in C-shaped section out of thin-walled hard tube by button, so
Thin-walled hard tube is withdrawn from into pipeline etc. afterwards, then with the outer wall of heater heating pipe, so far the leakage point on pipeline can be had
Inner wall of the pipe is repaired.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvements and modifications can also be made, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
